SHIRT s'rUn.

Application filed April 23,

This invention relates to a new and im-' proved method of making shirt studs and similar articles and to a new and improved shirt stud or the like.

One of the objects of this invention is to provide a shirt stud comprising a one piece body and a one-piece movable shank provided with an ornamental head which can be conveniently and cheaply manufactured.

Another object is to provide a device which shall be substantially dust-proof.

Another object is to provide a simple, durable, and eiiicient spring detent which shall releasabl 1 hold the shank in two positions.

Other objects of this invention will be set forth in the following description and drawings, which illustrate a preferred embodiment thereof, it being understood that the above general statement of the objects of this invention is intended merely to generally explain the same and not to limit it in any manner.

Fig. 1 is a front elevation showing the improved stud applied to a shirt.

Fig. 2 is a front elevation of the stud.

Fig. 3 is a side elevation of the stud, shown applied to a shirt. 7

Fig. 4 is an elevation of the tubing used for making the device.

Fig. 8 is a side elevation showing another step in the manufacture of the device.

Fig. 9 is a section on the line 9--9 of Fig. 8.

Fig. 10 is a sectional view, partially in elevation, showing the completed device, the shank being shown in its intermediate position.

Fig. 11 is a view similar to Fig. 10, the shank beingshown in its inner position.

Fig. 12 is a view similar to Fig. 10, the shank being shown in its outer position.

Fig. 13 is a view similar to Fig. 10, the

spring detent being omitted.

onthe line 5-5 of A piece of tubing 1 made of gold or any other metal, is provided with an aluminum core 2. The straight section 1 is bent by means {if suitable dies the like to provide 1926. Serial No. 104,018.

it with a leg l, which is formed as shown in Fig. 6, by the bending operation.

A hole 3 is now formed in the tube 1 and a depression in the aluminum core is simultaneously formed as shown in Fig. 6. The aluminum core is now removed by treatment with any suitable acid, which will not affect the gold tube. The removal of the core is facilitated by the formation of the opening 3.

A mandrel M, made of steel or other hard metal, is forced through the opening 3, so that the point of the mandrel emerges from the top of the leg 4:, as shown in Fig. 8. The cross-section'of mandrel M is non-circular, and this mandrel is preferably provided with two opposite, parallel and equal planar faces, and with two convex faces, as shown in Fig. 9. The mandrel M shapes the interior of the leg 4 so that its cross-section is no longer circular, and it is given a shape corresponding to the shape of the mandrel M.

The top of the leg 4 is now expanded and bent to form a head 9, this operation per se being well-known.

A shank 6, provided with two recesses 7 and 8 and having an ornamental head 10, is now inserted into the leg 4. The shank 6 has a shape corresponding to the shape of the mandrel M, so that it slides in the leg 4 without turning, and it fits snugly in leg l, to exclude dust as much as possible.

The shank 6 is placedin the leg A in the position shown in Fig. 3 (but without closing the end of tube 1) the ball 12 and the compression spring 11 are placed in position, and the end of the tube 1 is closed.

The compression spring 11 now forces the ball 12 against the shank 6, so that the ball 12 acts as a detent, to releasably hold the shank in either of the two positions shown in Figs. 11 and 12. In these positions. the ball 12 engages either the recess 7 or the recess 8.

When the parts of the device are in the position shown in Fig. 12. the body 1 can be forced through two adjacent stud-openings in a shirt S, so that said body portion 1 assumes the positioh shown inFigs. 1 and 3. By then pushing on the ornamental shank head 10, the shank is forced into the position shown in Fig. 3, to lock the two parts of the shirt to each other.

To remove the stud, the parts are moved into the position shown in Fig. 12,"whcn the stud can be readily pulled out.

It is obvious that the device can be readily manipulated, and that it is far more convenient to use than studs heretofore known.

The shank cannot be withdrawn from the leg 4, because the inner end of said shanltis provided with a hook-like extension 14.

An important feature of this invention is that spring detent means are provided which are independent ofthe tubing use: Hence, there is no need to makethis tubing resilient p .2. i

iTlie flange 9 should be so wide tnat it does not passtl'irought'he shirt opening. irpreferred embodiment of this invention has been described, but it is clear that nunierou s changes andoniissions could beinade without de'parting froi'n its spirit. In particular the claims for the article aren'ot to be restricted to any )a ticular method of producing the same. Vhenevera shirt-stud is referred to in the description or claims, this'is to be understood as referring to and including all similar articles.

I claim ,1. A shirt stud comprising a hollow body portion having a hollowleg provided with an enlarged top portion, said body portion and said leg comprising two parts of an integral bent tube the cross-section oi. said leg being non-circular, said leg having an opening adjacent the inneiend thereof, and a slidable 'shankhaving anon-circular cross section "corresponding to the cross-section of said leg and slidably fitting within said leg and being held ifronrturning-in said leg, said shank having a head.-

2. A shirt stud coniprisinga body portion having a hollow leg provided with an opening adjacent the inner end'thereof, a sli-dable shanlolocated within said leg, and spring d-ctent means independent of the niaterial or said leg and adapted to releasablyengage said shank, said shank having a head.

"3.- A shirt stud con'ipi'ising a hollow body portion having a hollow leg,' said leghaving an opening adjacent the inner end thereof tion and ail olloi vl 'ing at the inner end thereof, said shanl ing two concave recesses on the face the eet ii 'zge'said ball to a slidable shank having a head and located within said leg; and spring detent means located in said body portion and adapted to engage said shank.
